Question
In a town, 30% of the population is ineligible to vote.
Among those eligible, 50% are women. If 2/5 of eligible men and 1/5 of eligible women voted, find the ratio of male to female voters who voted.Solution
ATQ,
Let the total population be '100n'
Eligible voters = 0.70 × 100n = '70n'
Eligible female voters = 0.50 × 70n = '35n'
Eligible male voters = 70n - 35n = '35n'
Males who voted = (2/5) × 35n = '14n'
Females who voted = (1/5) × 35n = '7n'
Required ratio = 14n : 7n = 2 : 1
